The 4 pins on the board that do not have anything soldered to them
connect to the
PMIC and can supply voltage from a 3.7v li cell you also need a
thermistor and a 75k resistor .
The PMIC can use the battery voltage and when on AC in can charge the
battery

Hi Evilwulfie,
Can you please explain. I am quite confused here. What internal
battery are you talking about? Others also please do not hesitate to
point out what I am missing here.
Thanks in advance.
Kind Regards,
Aditya

I use the built in battery and it works great I Can monitor it as well

Don't know how one could do that....
/Although the PMIC supports direct connection of a Li-ion battery
(including charging), this functionality is not officially
supported on any BeagleBone. Nevertheless, the terminals for this
are available on an unplaced header (pins labled TP5-TP8) for
experimentation. /

The PMIC has registers you can read to see what source you

I think you will need to do it by adding some hardware to
detect if external power supply is present or not. If
external supply is absent and you are executing some code
then you are on battery. Simple comparator circuit should do
it.

I do not know if it is also true for PocketBeagle, but
there is a tool rc_battery_monitor which shows the
voltage at the power supply jack. So you may just look
into the sources of the tool.

I am using and OSD3358 based PocketBeaglish Board.
I need to figure out if the board is running from
external power or the LiPo battery,
Is there an easy means of doing so ?
Something in sysfs maybe ?
